It is because it takes 3 months for Potash to become available in the soil. You always have to plan ahead when you are using Potash or, no matter how much you put on your tater plants they won't be able to access it.

Not enough water or not enough nutrients. My guess is water.

I just read about Determinate and Indeterminate potatoes. Which varieties of Indeterminate potatoes do well in Zone 10A?

Check on google what varieties are indeterminate and then see if any in your area.

How late can you start growing potato’s? My first batch was planted March 20 but plants are already wilting back and I was wondering if I could plant more in June?

I live in Zone 10A and have been growing russet and golden potatoes in grow bags and large containers here for about three years, and I notice I can plant them year-round and they will grow, just slower in winter, and if we get an occasional frost, it may kill the top, and when temps hit around 100 or hotter the potato tops may die off also. No matter what time of year, my potatoes often grow for a few months and then the tops start to die off no matter the season or conditions, but I don't know why, so when that happens, I'll reduce the watering for a couple weeks and then harvest. I try to do "succession" planting, so I always have some potatoes growing, and am still experimenting with what works best, especially trying to learn more about correct watering for the Zone 10A conditions. I do have better success, producing more and larger potatoes, with 10-20 gallon and larger containers than the 7-gallon fabric grow bags.

Are you looking for SWEET potatoes or regular potatoes ..... I think your climate is better suited for Sweet potatoes -- they are different (different families) and therefore have different instructions: The ideal soil temperature range for planting potatoes is 45 to 50 degrees Fahrenheit (7 to 10 degrees Celsius). After planting, the ideal temperature for growing potatoes is 60 to 70 degrees Fahrenheit (16 to 21 degrees Celsius). Potatoes do best in fertile, well-drained soils. However, potatoes will grow in many types of soils. Soils that are poorly drained tend to produce poorly shaped potatoes and tuber rot. Potatoes do well across a wide range of pH, but prefer slightly acidic soils; a soil pH of 5.3 to 6.0 is typical for potato production. If your soil is more acidic than this, mixing in wood ash will help raise the pH and make your soil more alkaline. Sweet potatoes (Ipomoea batatas) are close cousins of morning glory and only distantly related to traditional potatoes. They are tender, so must be protected from frost, and like heat, full sun and regular watering. They crop best at temperatures of 21–26°C (70–80°F) PLEASE CLARIFY which type of potato.
